Offered here is a Chambers golf ball marking machine that was patented in the UK in 1910 (pat. 18712).  Stamped "Made in England 2200" on top, this fascinating contraption appears to be in working condition, at least as far as it was tried. When pushed in and rotated, the front knob selected whatever number or letters were desired. When pushed down, the handle moved lower in order to stamp the selected letters/numbers onto the ball. Everything moves just fine, but it was not tested to see if it would actually mark a ball. Place your bet now!  Base measures 11 x 4"and is 8" high. Weighs 8 lbs.  Built like a tank!
